Powder processing is a key and fundamental step laying the basis for any shaping processes.

Due to our experience and powder processing facility we can process all types of ceramic and inorganic powders including:

  • Alumina
  • Zirconia
  • Oxides and mixed metal oxides
  • Minerals
  • Clay

We have the equipment for preparing highly homogenous powders and mixtures with different particle size distribution and/or composition. We work with small scale, single powder batches from gram scale up to medium scale production runs.

We provide:

- Spray dried powder with a tunable particle size distribution between 150 and 600µm.

- Milled particles as small as 500 nm

Our powder processing facility is equipped with state-of-the-art machinery to handle all process operations for:

  • Spray drying
  • Pelletizing
  • Wet/dry milling
  • Drying
  • Calcining
  • Sintering
  • Size and size distribution classification
  • Analytical testing


We can process with any size batches or samples you have and provide a full characterisation.

Dry pressing is one of the most simple technique for high volume fabrication of ceramic components with accurate dimensional specifications.
Flowable powders are compacted in a metal die set parts and afterwards sintered at high-temperatures for strengthening and conferring mechanical stability. We can design dies with appropriate specification for manufacturing both simple and complex geometries, composite materials and components to meet desired properties.

Thanks to our know-how we can offer a wide range of solutions to meet the specific requirements of your application. 

Slip casting
is a method for powder-based shaping of ceramic part with a long history. Slip casting is nowadays widely used both in the traditional and technical ceramic industry. Ceramics slurries (slips) consisting of suspended ceramic particles and eventually deflocculants (dispersants), and binders are poured into a plaster mould. The water in the slip is drawn into the plaster and creates a wall of consolidated material. 

By slip casting we can realise:

  • Crucibles of various sizes amorphous silica for silicon melting 
  • Monolithic and pipes of silicon carbides
  • Crucibiles and plates made of allumina and zirconia

The injection moulding process employs very fine ceramic powders compounded with thermoplastic binders to produce a homogeneous pelletized feedstock. The feedstock is then carried and injected into a cavity mould.
Moulds, that can be designed with customised configurations, permit to form net shaped parts. After forming, the parts are then thermally treated to remove the binder (pyrolysis) and sintered at high temperatures to obtain fully dense ceramic parts. Injection moulding is ideal for high-volume production of complex, tight-tolerance components.

With our design and manufacturing expertise, we can support the development of your future products from prototype through to full volume production.

Tape casting is a forming method for producing flat, thin tapes, with thickness between 0.1-2.0 mm. A ceramic slurry is spread onto a flat movable carrier surface and passes beneath a doctor’s blade to control the tape thickness. The solvents contained into the slurry evaporate and leave a flexible tape that can be further processed. Tape casting is employed for manufacturing different products such as multilayered inductors, multilayered varistors, piezoelectrics, ceramic fuel cells and lithium ion battery components.

By tape casting Petroceramics can realize parts of different materials including alumina, zirconia and silicon carbide.
